What else can I help you with?
What will happen to the cells of an apple pieces if they are in salty water?
The cells of the apple pieces will lose water through osmosis due to the higher concentration of salt in the water compared to the inside of the cells. This will cause the cells to shrink and become dehydrated, potentially leading to wilting and a change in texture.
What do cells contain so that they dont become waterlogged?
In plants, large spaces inside cells called vacuoles can hold water. In animal cells, the cell membrane contains water transporters or water channels that help in removind water if there is too much water inside cells
What main solvent is inside all cells?
water, water everywhere
What will happened to cells when it is exposed in isotonic solution?
In an isotonic solution, cells will maintain the same shape and size because the concentration of solutes inside and outside the cell is equal, leading to no net movement of water. This prevents the cell from either shrinking or swelling due to water moving in or out.
Why is the shape of guard cells important its function?
The shape of guard cells is crucial for their function in regulating gas exchange and water loss in plants. When guard cells swell with water, they bend and create an opening called a stoma, allowing carbon dioxide to enter for photosynthesis while releasing oxygen. Conversely, when they lose water, they become flaccid and close the stoma to reduce water loss. This dynamic ability to change shape enables plants to maintain homeostasis in varying environmental conditions.
What do cells do in a isotonic solution?
Usually this question is in reference to a RBCs (red blood cells). When there is the same amount of water molecules on the outside of the cell as the inside of the cell, so there is no change in the shape of the cell.
What is the role of guard cells do in the leaf?
Guard cells change shape to open and close stomata. When they are flaccid, the stoma is closed. When they are full of water and firm, the stoma is open. There are 2 guard cells controlling a stoma. Water enters guard cells by osmosis and they change shape.
How does the shape of a cell change in an isotonic solution?
In an isotonic solution the shape of a cell remains unchanged. This is because the movement of water inside the cell equals the movement of water outside the cell.
What will happen to the cells of an apple pieces if they are in salty water?
The cells of the apple pieces will lose water through osmosis due to the higher concentration of salt in the water compared to the inside of the cells. This will cause the cells to shrink and become dehydrated, potentially leading to wilting and a change in texture.
Why do guard cells change shape?
The guard cells become turgid when the plant is well hydrated. The turgidity changes their shape to open the stomata. When the guard cells are flaccid, the stomata close and the plant conserves water.
Is water found in the cell membrane?
The same way that air influences the shape of a balloon. When the cell is in the proper environment water enters the cell and it is the proper shape. When the solute concentration outside the cell is too high the water leaves the cell and it shrivels.
Why the potato becomes turgid in water in osmosis?
When a potato is placed in water, the water concentration outside the potato cells is higher than inside. This creates a concentration gradient that drives water molecules into the potato cells through osmosis, causing the cells to swell and the potato to become turgid. The cell wall of the potato cells helps maintain the shape and prevents them from bursting.
How is water important in the plants shape?
Water is important in the plants shape as the pressure from the water in the cells help to keep the plants shape. When a plant is devoid of water it begins to droop, this means there is no water in the cells to help keep it upright.
